At the east gate she moved her sunglasses up onto her forehead and gave the guard a big smile. “Hi, Harry,” she said. “Mitzi Prentice, and this here’s Mr. Miller, come for a look at the Lattimore house on Saguaro Circle.”

“Miz Prentice,” he said, returning her smile and nodding at Keller. He consulted a clipboard, then slipped into the shack and picked up a telephone. After a moment he emerged and told Mitzi she could go ahead. “I guess you know how to get there,” he said.

“I guess I ought to,” she told Keller, after they’d driven away from the entrance. “I showed the house two days ago, and he was there to let me by. But he’s got his job to do, and they take it seriously, let me tell you. I know not to joke with him, or with any of them, because they won’t joke back. They can’t, because it might not look good on camera.”

“There are security cameras running?”

“Twenty-four hours a day. You don’t get in unless your name’s on the list, and the camera’s got a record of when you came and went, and what car you were driving, license plate number and all.”

“Really.”

“There are some very affluent people at Sundowner,” she said, “and some of them are getting along in years. That’s not to say you won’t find plenty of people your age here, especially on the golf course and around the pool, but you do get some older folks, too, and they tend to be a little more concerned about security. Now just look, David. Isn’t that a beautiful sight?”

She pointed out her window at the golf course, and it looked like a golf course to him. He agreed it sure looked gorgeous.

The living room of the Lattimore house had a cathedral ceiling and a walk-in fireplace. Keller thought the fireplace looked nice, but he didn’t quite get it. A walk-in closet was one thing, you could walk into it and pick what you wanted to wear, but why would anybody want to walk into a fireplace?

For that matter, who’d want to hold a prayer service in the living room?

He thought of raising the point with Mitzi. She might find either question provocative, but would it fit the Serious Buyer image he was trying to project? So he asked instead what he figured were more typical questions, about heating and cooling systems and financing, good basic home-buyer questions.

There was, predictably enough, a big picture window in the living room, and it afforded the predictable view of the golf course, overlooking what Mitzi told him were the fifth green and the sixth tee. There was a man taking practice swings who might have been W. W. Egmont himself, although from this distance and angle it was hard to say one way or the other. But if the guy turned a little to his left, and if Keller could look at him not with his naked eye but through a pair of binoculars-

Or, he thought, a telescopic sight. That would be quick and easy, wouldn’t it? All he had to do was buy the place and set up in the living room with a high-powered rifle, and Egmont’s state-of-the-art home burglar alarm wouldn’t do him a bit of good. Keller could just perch there like a vulture, and sooner or later Egmont would finish up the fifth hole by four-putting for a triple bogey, and Keller could take him right there and save the poor duffer a stroke, or wait until he came even closer and teed up his ball for the sixth hole (525 yards, par five). Keller was no great shakes as a marksman, but how hard could it be to center the crosshairs on a target and squeeze the trigger?

“I bet you’re picturing yourself on that golf course right now,” Mitzi said, and he grinned and told her she got that one right.

From the bedroom window in the back of the house, you could look out at a desert garden, with cacti and succulents growing in sand. The plantings, like the bright green lawn in front, were all the responsibility of the Sundowner Estates association, who took care of all maintenance. They kept it beautiful year-round, she told him, and you never had to lift a finger.

“A lot of people think they want to garden when they retire,” she said, “and then they find out how much work it can be. And what happens when you want to take off for a couple of weeks in Maui? At Sundowner, you can walk out the door and know everything’s going to be beautiful when you come back.”

He said he could see how that would be a comfort. “I can’t see the fence from here,” he said. “I was wondering about that, if you’d feel like you were walled in. I mean, it’s nice-looking, being adobe and earth-colored and all, but it’s a pretty high fence.”

“Close to twelve feet,” she said.

Even higher than he’d thought. He said he wondered what it would be like living next to it, and she said none of the houses were close enough to the fence for it to be a factor.

“The design was very well thought out,” she said. “There’s the twelve-foot fence, and then there’s a big space, anywhere from ten to twenty yards, and then there’s an inner fence, also of adobe, that stands about five feet tall, and there’s cactus and vines in front of it for landscaping, so it looks nice and decorative.”

“That’s a great idea,” he said. And he liked it; all he had to do was clear the first fence and follow the stretch of no-man’s-land around to wherever he felt like vaulting the shorter wall. “About the taller fence, though. I mean, it’s not really terribly secure, is it?”

“What makes you say that?”

“Well, I don’t know. I guess it’s because I’m used to the Northeast, where security’s pretty up front and obvious, but it’s just a plain old mud fence, isn’t it? No razor wire on top, no electrified fencing. It looks as though all a person would have to do is lean a long ladder up against it and he’d be over the top in a matter of seconds.”

She laid a hand on his arm. “David,” she said, “you asked that very casually, but I have the sense that security’s a real concern of yours.”

“I have a stamp collection,” he said. “It’s not worth a fortune, and collections are hard to sell, but the point is I’ve been collecting since I was a kid and I’d hate to lose it.”

“I can understand that.”

“So security’s a consideration, yes. And the fellow at the gate’s enough to put anybody’s mind at rest, but if any jerk with a ladder can just pop right over the fence-”

It was, she told him, a little more complicated than that. There was no razor or concertina wire, because that made a place look like a concentration camp, but there were sensors that set up some kind of force field, and no one could begin to climb the fence without setting off all kinds of alarms. Nor were you home free once you cleared the fence, because there were dogs that patrolled the belt of no-man’s-land, Dobermans, swift and silent.

“And there’s an unmarked patrol car that circles the perimeter at regular intervals twenty-four hours a day,” she said, “so if they spotted you on your way to the fence with a ladder under your arm-”

“It wouldn’t be me,” he assured her. “I like dogs okay, but I’d just as soon not meet those Dobermans you just mentioned.”

It was, he decided, a good thing he’d asked. Earlier, he’d found a place to buy an aluminum extension ladder. He could have been over the fence in a matter of seconds, just in time to keep a date with Mr. Swift and Mr. Silent.

In the Lattimore kitchen, they sat across a table topped with butcher block while Mitzi went over the fine points with him. The furniture was all included, she told him, and as he could see it was in excellent condition. He might want to make some changes, of course, as a matter of personal taste, but the place was in turnkey condition. He could buy it today and move in tomorrow.

“In a manner of speaking,” she said, and touched his arm again. “Financing takes a little time, and even if you were to pay cash it would take a few days to push the paperwork through. Were you thinking in terms of cash?”
